Specification of Letters Patent.

Patented Nov. la, 1916.

Application filed November 1, 1915. Serial No. 59,007.

To all 'Lv/wm it m ag/ concern Be it known that I, EDGAR PATTEE, a citizen of the United States, residing at Santa Cruz, in the county of Santa Cruz and State of California, have invented new and useful Improvements in Belts, of which the following isa specification.

This invention relates to a belt adapted both for transmission and conveying purposes.

One of the objects of the present invention is to provide a simple, substantial exible metal belt adapted for use either as a conveying or transmission belt; furthermore, to

provide a belt which may be cheaply manufactured and which will be more iiexible and have greater wearing qualities and life than belts manufactured of leather, rubber, can-- vas, etc.

AnotherV object of the invention is to construct a flexible metal belt in which contact of metal to metal is eliminated and which will be practically noiseless when running.

Further objects v will hereinafter appear.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a plan view of the belt. Fig. 2 is a section on line 2 2, Fig. l, showing a filler applied to the belt. Fig. 3 isa perspective View, showing the interwindlngof the coils and the position of the pins. Fig. 4 1s a view similar to Fig. 1, of a modified form of the invention.

Referring to the drawings in detail, A indicates the belt in general. This belt is constructed of a series of interwound spiral coils .2, disposed parallel with relation to each other and having pins 3 passing therethrough. The outer ends of the coils are either secured together or to an endless eX- ible cable 4 constructed of rope, wire or any other suitable material. An edging having great flexibility and wearing quality 1s 1n this manner secured.

The interwinding of' the coils 2 which form the fabric of the belt is more clearly shown in Fig. 3 for which purpose of clear showing one of the pins 3 has been shown in dotted lines. From this view it will be seen that each individual coil is hinged to the adjacent coil and also upon the pin passing therethrough. This permits fiexiblhty 1n a line crosswise ofthe belt, as each coil hinges on the pin 3 and the adjacent coils to which they are interwound.

The belt constructed as shown in Fig. l can be used as a transmission belt by lagging the pulleys over which it passes with rubber or other suitable material, thereby obtaining the grip necessary. The pins employed may in this instance be rigid and to make the belt as noiseless as possible, it is desirable to construct the pins of a composition material, such as fiber, vulcanized rubber, etc. The belt,however, may be used as a conveyer for conveying purposes and it is desirable in that inst-ance to permit cupping of the belt. Itis therefore, necessary to provide pins that are flexible, and in actual practice rawhide pins have been found very desirable. For the purpose of preventing small material from passing through the interstices of the belt, it is sometimes desirable to ll the metal fabric with rubber, such as indicated at 6 in Fig. 2.

A belt thus constructed can be more cheaply manufactured than an ordinary 7- ply rubber belt, as it contains very much less rubber and also has a much greater life, as the wearing oli' of the top surface exposes the metal thus practically speaking produc` ing a metal-studded belt and as this is much more durable than the rubber, it naturally increases the life or wearing surface of the belt. The position of the exible rawhide pins permits the crosswise flexibility heretofore mentioned, and also permits cupping of the belt, which is very essential when conveying material. The pins passing through each individual coil prevent contact of metal to metal, thereby preventing generation of heat` and wear, which would otherwise take place It is furthermore, desirable to employ the pins where a rubber filler is employed, as it has been found that the rubber willadhere more readily to therawhide or the composition pin than to the metal. The pins employed in this manner have three functions: They first form pivots about which the coils may turn, thereby increasing the flexibility of the belt; they secondly space the coils apart to prevent contact of metal to metal, thereby reducing heat and unnecessary wear; and third, it is found that they act as binders for the filler employed. While a rubber filler is employed 1n most instances, it is obvious that any other suitable composition i performed.

The belt constructed as here shown, is not only cheap to manufacture, but is much more durable and longer-lived than most forms of belts now in use. It is furthermore, flexible in all directions and practically noiseless when'unning.

While the pins employed are here shown as positioned crosswise to the belt, it is obvious that they may be angularly disposed, as indicated by dotted lines at 5, inv

Fig. 4;. A still greater flexibility canbe produced by so placing the pins.

Another important feature will be as follows: Referring to Fig. 1, it will be seen that angularly disposed channels are formed when constructing a metal fabric of the character shown. These angularly disposed channels when filled with rubber or like material when passing over a pulley will gradually bend from one end to the other, as they pass over and have therefore, less ,tendency to break the filler, as would otherf wise be the case.

When using a belt, such as shown in Fig. 4l in place of employing a filler, it is -sometimes possible to place a canvas or rubber belt on top of the belt proper. The belt then acts as a carrier for the surface belt and as the surface becomes worn, it is only necessary to replace it with a new belt. The covering belt may be suitably secured to the outer edge of the main belt A and by placing it in this manner it will permit it to be quickly removed as conditions may require.

The materials and finish of the several parts of the belt may be otherwise such as the judgment and experience of the manu-- facturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention`,what I claim and desire t0 secure by Letters Patent is 1. A belt composed of a series of inter connected wire coils, non-metallic pins passed through thecoil connections, and a rubber filler inclosing the coils and pins.

2. A belt composed of a series of interconnected wire coils, and non-metallic pins passed through the coil connections to space the coils and prevent adjacent metal parts thereof from contacting thereby to reduce wear and heat generated by rubbing of the parts against each other.

3. A belt comprising a series of interwound Wire coils, and non-metallic .pins passing through the interwound connections of the coils.

4. A belt comprising a series of interwound wire coils, and non-metallic flexible pins passing.through the interwound connections of the coils.

5. A belt comprising a series of interwound wire coils, and rawhide pins passing through the interwound connections of the coils.

6. A fabric comprising a series of interwound wire coils, and non-metallic pivot members passing through the interwound connections of the coils.

7. A belt comprising a series of interwound wire coils, pins passing through the interwound connections of the coils, and an endless cable on each side or edge of the belt to which the ends of the coils are secured.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
